How to set up intermatic t104m to work with two speed motor


T104 cannot be easily set up to handle 2-speed motors
You need T106 timer with NO NC terminals.

Or you can use the T104 to control relay with NO NC terminals... relay would need 240 Volt coil. Problem is most relays with NO NC terminals are 120 Volt coil or rated too low amperage for motor.

Or move T104 clock motor wires to A and 1... connect 240Volt power to A and 1... then terminals 3-4 are dry and can be used to control any voltage relay coil (120 Volt for example).
When T104 is ON, then relay uses NC terminals to send power to low speed. When T104 is OFF, then relay uses NO terminals to send power to high speed.
Buying T106 timer is probably cheaper and simpler.

Where is the wiper relay


A wiring diagram doesn't show a relay, just a 25 amp fuse in fuse panel under driver's side of dash. Intermittent working is usually from a loose or poor or corroded connection, or the switch is old and tired, or the motor is old and tired.
Here is one way to check, if you have a test light: when the wipers are not working with wiper switch on high, and key is on, pull off the connector to the wiper/washer motor module (in the engine bay, on the firewall) and check if the purple wire has power. If it does, you probably need to replace the module. Inside the module is a park relay switch (to return wipers to down position when turned off) and a circuit breaker between the motor and ground.
If the purple wire does not have power when key is on and wipers on high, the connection is lost between the switch and the module, or the switch may be malfunctioning. The switch has 5 wires, white wire from 25 amp fuse (power in to switch), a pink wire (for the washer motor), a purple wire (high speed wipers), a dark green wire (low speed wipers), and a gray wire (for the park relay switch inside the wiper/washer motor module). If you see a yellow wire also at the module, that is part of the low speed wiper circuit (the dark green wire) coming from the park relay switch and then to the motor.
Good luck. Post back if further questions, or need more help.

1992 chevy C1500: Heat works on low speed, no medium, and high only works intermittantly.


On any other vehicle it sounds like the blower fan switch.
The fan switch provides power or ground to the resistor and there would be a high speed blower relay to bypass the resistor.
But in your case the fan switch is part of the controller.
I don't have a diagram for a 92 but the 94 model shows relays for low medium and high speeds. Each relay gets power from a fuseable link. The high relay gets power thru the low relay if the low relay is not engaged.
If you have the model with 3 relays you may need to check them.

Need to change a broken blower motor in RUUD central air unit. Old central air blower motor (GE electric) was connected with brown and orange wire to 15 MHD capacitor. Another orange wire from central air...


on the motor should be a diagram detailing the wires. brown white goes to either side of the capacitor and brown wire to other side of capacitor. hi speed goes to normally open contact on the indoor fan relay and the wire designated common on the motor goes to the other side of power from the relay contacts.

Furnace transformer/fan-relay wiring to fan-motor


All you need is 2 fan speeds, 1 for cool and 1 for heat. Leave the low speed disconnected. Normally we have high speed for cooling, and med. or low for heat. So either speed connected to the heating circuit is fine.

1998 olds delta 88 lost fan control, ac control, and rear window control all at once have power to fuses and tried differnt switch assembly in dash


It might not be a fuse that goes to that it might be a relay thats under your hood in the fuse box. Just a idea for you to try. Hope this works out for you.

Replaced fan relay but now lowing fuses


This might be a ground wire loose somewhere. Or a hot wire exposed to a ground. Electrical problems are the worst part of a car to fix. Try to replace just the wires or the entire harness to the fan relay.
Hope this helps.

I have an A.O. Smith f48l47a50 blower motor, and I need help with wiring. First it's a 460v,1phase,1/2hp,975rpm,3spd motor. My question with the wiring is do I need to supply a wire for line power? I know...


are you SURE its 460volt single phase??? that voltage is normally a 3phase motor voltage,and color of wires is right for 480/277, but that would be 3 phase.....not saying your wrong,just make sure

Lincoln 2000 town car Blower doesn't work at HI-MED-LOW speeds...


it is called blower motor resistor , should be close to blower motor , you will see a plug type connector with two screws , remove the screws and there should be a resistor inside the cover for the motor, swap with new and reassemble

No high speed on blower motor


if motor works on heat, but not on cool ,then the low speed is energized by the heat strip or control board .if the motor doesn't run in high on cool, then the fan relay or black high speed tap from the board is not being energized. usually its the fan relay ,which is only a factor in cool in high speed fan mode. try turning fan to on at stat. that energizes fan relay and blower should run in high. gently tap the side of the fan relay and see if fan comes on all of a sudden. if it does the relay is bad. change it wire for wire label all wires and use exact replacement relay unless you know how to read wiring diagram then you can use a 90-340 generic fits all replacement. trace motor power wires back to relay or control board to find where they are fed from.
